FRAME-ADJUSTER.

Applications filed February 11, 1919. SerialNo.

To all whom it may concern:

Be it known that I, CLARENCE E. Home, a citizen of the United States ofAmerica, 1e siding at l-lenryetta, in the county ofOkmulgee and State ofOklahoma, have invented new and useful Improvements in Fram'ea idjustersof which the following is a specification.

The object of the invention is principally to provide a mechanism foruse'n conjunction with a cultivator of the toothed-drum variety, so thatthe said drum may be read i'ly" and quickly elevated to free it from theground or just as quicltly lowered to brin it in operative contact withthe ground. The cultivator with which the improved attachment isdesigned for use is that shown in the applicants Patent No. 1,289,176,dated Dec. 31, 1918. The improved mechanism is provided with alatch-control lever positioned adjacent the cultivator seat and thislever is operatively connected with two stub axles on which thecultivator wheels are journaled. Thus the operation of the lever lowersthe cultivating drum until the latter contacts with the ground andthereafter raises the wheels to free them from the ground. It may alsobe manipulated to ei feet the reverse of these operations and further itmay be adjusted to regulate the depth 30 which the teeth of the drumpenetrate the ground.

As illustrated and described, a specific :mbodiment of the invention isadhered to not to this embodiment it is not to be retricted. Actualpractical use may suggest ertain desirable changes or alterations and beright is claimed to make any falling rithin the scope of the subjoinedclaim.

In the accompanying drawings forming art of this application and inwhich the Line numerals of reference designate the tIIlG parts Figure 1is a side elevation of the culti- LtOI showing the wheel-elevatingmechasm attached thereto.

Fig. 2 is a perspective view of the mechllSll'l per cc.

Fig. 3 is an enlarged sectional View on e line 3-3 of Fig. 2.

As shown, the invention is applied to the ltivator generally designatedA, this culator having the inverted U-shape frame Specification ofLetters Patent.

in which the drum 1 is carried, the drum being ofthe usual character andprovided "with soil-engaging teeth, as is shown. i shape frame is formedwith the two legs 2 and-with the transverse member 3 at the center ofwhich the seat 4 is carried. The legs 2 are, as is shown, channel shapein cross section, each legbeing'provided with longitudinal side flanges5 and 6 which are undercut so that the plates 7 may be carried by thelegs for longitudinal or vertical movement there along, the edges of theplate lying behind the undercut portions of the flanges. Each plate 7adjacent its lower end carries a stub axle 8 which is attached to-it byappropriate bolts on these stub axles-the wheels 10 are rotatinglymounted; "Directly above the stub axle there are pinions 11, thesepinions being positioned adjacent the upper ends of the plates and eachpinion being rotatably mounted 011 a stub 12 carried by its attendantplate.

The flange 5 tain points in its length is provided with rack teeth 13with *which the teeth of the pinion 11 mesh. 'VVhile the flange 6 on theinner end of that portion which overlies the plate 7 is provided with aT-slot in which a longitudinally T-shaped rib 14 slidingly engages. Thisrib being formed on the back edge of a rail 15 is provided with rackteeth 16 also meshing with the teeth of the pinion 11.

The upper ends of the legs 2 are extended above the transverse member 3and these extending ends are each provided with a bearis journaled, thelatter being positioned above the transverse member 3 and extendingacross the frame beneath the seat 4. That this shaft may be rocked bythe operator or driver of the machine and secured in any position towhich it may be rocked, there is provided a tooth segment 18 which ismounted on the transverse member 3 beside the seat 4 and this segment isformed with a bearing for the shaft 17 at the center of the rack. Fixedto the shelf 18 beside the segment, there is a hand-lever l9 and thishand-lever carries a manually operated spring latch 20 which isengageable with any one the segment so that the lever may be moved ofeach leg 2 between cerof the teeth of formed on the flange forwardly andrearwardly and locked in any position to which itmay be moved thusmaking it possible to rock the shaft and also look it in any position towhich it may be moved, since the lever is secured to the shaft. ,1 t fThe shaft 3 protrudes from its bearings a sufficient distance to permitthe attachment on each end of asegmental gear 21,

these two segmental gears measuring with the teeth of the rails 157011either side of the frame. It is thus apparent that rocking movementimparted to the shaft will result in longitudinal movement up or downbeing imparted to the rails 15, withthe result that the pinions 11 arerotated on their stubs,

Such rotation of the pinions will obviously affect the raising orlowering of the plates 7. since the pinions mesh with the teeth 13 6.,Thus as the lever 20 is moved rearwardly or forwardly the plates 7 areraised or lowered with the consequent raising or lowering of the wheels10, thereby causing the drum to be lowered to' the ground leaving thewheels elevated or causing the wheels to 'be moved to the ground withthe consequent elevation of the drum if the latter be upon the ground.Obviously the position of the plates regulated and thus the positions ofthe plates and carrying may be frame, of wheels carried by the legs ofsaid frame, the legsof the frame being channel shaped and formed withundercut flanges, plates slidably mounted on the frame behind saidflanges, stub axles mounted on the the cultivator wheels pinionsrotatably mounted on said plates, one flange of each leg being formedwith rack teeth, the pinions meshing with the a rail'slidably teeth -onthe two flanges, mounted in theother flange of each leg, said railsbeing formed with teeth and meshing with the pinions, a transverselydisposed shaft journaled in the said legs, segment gears mounted on theshaft and meshing with the rails, and alatch control manually operable elever connected with the shaft whereby the latter may useful purposeherein s ecified.
